Description

Technical Field

[0001] This invention belongs to the field of fire extinguishing device technology, and in particular relates to a remote-controlled fire extinguishing device for a hot smoke generator spraying drone. Background Technology

[0002] In various fields such as agricultural plant protection, forestry pest control, disinfection and epidemic prevention, and environmental management, high-altitude smoke spraying has become a key means to meet the needs of large-scale pest control due to its ability to achieve large-scale and efficient pesticide coverage. Traditional smoke spraying operations mostly rely on ground equipment or manned aircraft. Ground equipment is limited by terrain and is difficult to cover complex areas such as mountains and forests, and its operation efficiency is low. With the rapid development of drone technology, smoke spraying drones, which have autonomous flight, precise control, and flexible take-off and landing characteristics, are gradually replacing traditional equipment and becoming the core carrier of high-altitude smoke spraying. As the core operating component of smoke spraying drones, the hot smoke generator produces smoke-like pesticides through combustion heating or mechanical atomization, which can achieve uniform diffusion and deep penetration of pesticides. It is especially suitable for scenarios with high requirements for pesticide coverage density, such as pest and disease control and disinfection.

[0003] When the hot air hood is working, it releases continuous high temperatures. These high temperatures not only affect its own casing, pipes and other components, but also radiate and conduct to the adjacent drone body. This can easily lead to spontaneous combustion of fuel residue in the hot air hood, fire caused by aging seals, or melting and burning of plastic parts and wiring insulation layers of the drone, thus posing a risk of spontaneous combustion of the entire drone. Since operators cannot directly intervene when the drone is operating at high altitude, a fire can easily cause equipment damage, crashes, or even secondary disasters on the ground.

[0004] To address these issues, a remote-controlled fire extinguishing device for hot smoke generators and smoke-spraying drones is proposed. Summary of the Invention

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] like Figures 1-5 As shown, a remote-controlled fire extinguishing device for a smoke-spraying drone includes a controller 2 installed on the drone body 1. The drone body 1 houses a smoke-spraying machine 3 and a camera mechanism 4. The camera mechanism 4 includes a first motor 401 installed inside the drone body 1. A mounting slot for the first motor 401 is provided on the side wall of the drone body 1. A rotating frame 402 is fixedly connected to the output end of the first motor 401. A monitoring probe 6 is rotatably connected to the inner wall of the rotating frame 402. A second motor 7 is fixedly connected to the side wall of the rotating frame 402. The output end of the second motor 7 passes through the rotating frame 402 and is connected to the monitoring probe 6. The device also includes:

[0028] The remote-controlled fire extinguishing component 8 is installed on the bracket of the drone body 1. The remote-controlled fire extinguishing component 8 includes a fire extinguisher 81. A motor frame 82 is fixedly connected to the end of the fire extinguisher 81. A micro stepper motor 9 is fixedly connected to the side wall of the motor frame 82. A cam 10 is fixedly connected to the output end of the micro stepper motor 9. The cam 10 is located above the handle of the fire extinguisher 81. The fire extinguisher 81 body is connected to the drone body 1 through the connecting component 11. By installing the remote-controlled fire extinguishing component 8 on the drone frame and ensuring that the nozzle is precisely facing the smoke generator 3 and the drone, the remote-controlled fire extinguishing is achieved through the linkage of components such as the micro stepper motor 9 and the cam 10. It can quickly spray agents to extinguish the fire. At the same time, it is equipped with a rotatable camera mechanism 4 to transmit the ignition point and fire situation in real time, which makes it easy for operators to grasp the drone's operating status in a timely manner and intervene precisely. This effectively avoids equipment damage, crashes, and secondary disasters on the ground caused by the spread of the fire, and significantly improves the safety and reliability of the smoke generator 3's high-altitude smoke spraying and drug application operation.

[0029] A cleaning component 14 is disposed inside the drone body 1. The cleaning component 14 includes a first small electric push rod 141. A receiving groove is opened on the side wall of the drone body 1 behind the camera mechanism 4. The fixed end of the first small electric push rod 141 is located in the receiving groove. A second small electric push rod 142 is fixedly connected to the output end of the first small electric push rod 141. A dust cover 15 is fixedly connected to the output end of the second small electric push rod 142. A water tank 16 is fixedly connected to the output end of the second small electric push rod 142. Two support frames 17 are connected to the left side wall of the water tank 16. Rotating rollers 18 are rotatably connected to the inner walls of both support frames 17. A micro-roller is fixedly connected to the front side wall of the upper support frame 17. The output end of the micro motor 19 passes through the support frame 17 and is connected to the rotating roller 18. The two rotating rollers 18 are covered with the same wiping belt 20. A component for cleaning surface dust is added to the camera mechanism 4 of the device, which can effectively remove smoke residue, dust and other debris generated by high-altitude flight and smoke spraying operations from the camera lens. This avoids problems such as unclear transmission of fire images and inaccurate identification of the ignition point caused by lens obstruction or blurring. It ensures that the operator can accurately grasp the fire dynamics and working conditions of the drone and the smoke generator 3 in real time, and provides clear visual support for the remote triggering of the fire extinguishing device to quickly and accurately extinguish the fire. This further ensures the safety of the smoke generator 3 and the reliability of the fire extinguishing response during high-altitude operations of the smoke spraying drone.

[0030] The connecting component 11 includes two first clamps 111, and two second clamps 112 are fitted on the outer wall of the drone body 1 bracket. A connecting seat 12 is fixedly connected to the side wall of the second clamp 112, and a slot is opened on the side wall of the connecting seat 12. A locking block 13 that matches the slot is fixedly connected to the side wall of the first clamp 111. The front and rear side walls of the connecting seat 12 are both provided with fixing grooves, and the fixing grooves are fixed to the locking block 13 by bolts. This effectively resists the vibration and turbulence during the flight of the drone, avoids problems such as the nozzle of the fire extinguisher 81 shifting or the fire extinguishing trigger mechanism jamming caused by loosening or displacement of parts, and ensures that the remote control fire extinguishing device always maintains the preset installation posture and working accuracy. It ensures that the fire extinguisher 81 handle can be pressed accurately and the agent can be sprayed in a directional manner when a fire occurs. At the same time, it improves the overall structural stability and anti-interference ability of the device, and further enhances the safety and fire extinguishing reliability of the high-altitude operation of the hot smoke machine 3 smoke spraying drone.

[0031] A miniature water pump 21 is connected to the side wall of the water tank 16. The water inlet of the miniature water pump 21 is connected to the water tank 16. A longitudinally arranged spray pipe 22 is connected to the side wall of the water tank 16 near the wiping belt 20 through a bracket. Multiple atomizing nozzles 23 are fixedly connected to the side wall of the spray pipe 22 near the wiping belt 20.

[0032] Two auxiliary plates 24 are fixedly connected to the side wall of the connecting seat 12. The auxiliary plates 24 have a groove 25 on the side wall near the clamping block 13. The side wall of the auxiliary plates 24 is connected to a clamping plate 26 located in the groove 25 by bolt thread.

[0033] The inner walls of the first clamp 111 and the second clamp 112 are both fixedly connected with friction pads 5, which are made of rubber.

[0034] The operating principle of this invention is explained as follows: When the UAV body 1 carries the smoke generator 3 for operation, the controller 2 detects through the monitoring probe 6 that the smoke generator 3 or the UAV body 1 is spontaneously combusting due to high temperature. The controller 2 will then send the detection information to the operator through the wireless communication module. The operator can then send an electrical signal to the controller 2 through the remote control switch. After receiving the electrical signal, the controller 2 will control the micro stepper motor 9 to work. The micro stepper motor 9 will drive the cam 10 to rotate at a certain angle. The cam 10 will squeeze the handle of the fire extinguisher 81, thereby causing the powder inside the fire extinguisher 81 to be sprayed through the nozzle onto the smoke generator 3, thus achieving the effect of extinguishing the fire. This effectively avoids equipment damage, crashes, and secondary disasters on the ground caused by the spread of the fire, and significantly improves the safety and reliability of the smoke generator 3 smoke spraying UAV high-altitude smoke spraying and pesticide application operation.

[0035] When the operator observes that the monitoring probe 6 is blurry on the display screen of the remote control handle, the operator can send an electrical signal to the controller 2 via the remote control handle. Upon receiving the electrical signal, the controller 2 will control the first motor 401 and the second motor 7 to operate. The first motor 401 and the second motor 7 will drive the monitoring probe 6 to rotate towards the cleaning assembly 14. Then, the controller 2 will control the first small electric push rod 141 to operate. The first small electric push rod 141 will drive the second small electric push rod 142 and the water tank 16 to move downward to the designated position. The water tank 16 will then drive the wiping belt. The wiping belt 20 is aligned with the lens of the monitoring probe 6. Then, the controller 2 controls the second small electric push rod 142 to work. The second small electric push rod 142 will drive the wiping belt 20 to contact the lens. Subsequently, the controller 2 controls the micro motor 19 to work. The micro motor 19 drives the wiping belt 20 to rotate through the rotating roller 18. The controller 2 also controls the micro water pump 21 to work synchronously. The micro water pump 21 will spray the cleaning liquid in the water tank 16 through the spray pipe 22 and the atomizing nozzle 23 onto the wiping belt 20 to wet the wiping belt 20. Thus, the wet wiping belt 20 can be used to clean the impurities on the lens surface.
